Operation method for mounting the second hard disk on Linux

After logging in remotely SSH to the Centos server, do the following

Reminder: The mounting operation will clear the data. Please confirm that the mounting disk has no data or is not in use

Step 1: List all mounted disk commands: disk -h

[root@gluster_node1 ~]#df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/VolGroup-lv_root

35G 25G 8.3G 76% /

tmpfs 1.9G 0 1.9G 0% /dev/shm

/dev/sda1 485M 35M 425M 8% /boot

/dev/mapper/VolGroup-lv_home

33G 176M 31G 1% /home

fdisk -l

Check disk status

Tip: If you cannot confirm the device name of the data disk, use the df command to confirm the name of the system disk to eliminate the situation of mounting the wrong disk.

Step 2: Format hard disk command: fdisk /dev/sdb

Note: Continue to type manually at the arrow mark in the figure

Step 3: Create a partition command: mkfs.ext4 /dev/sdb1

Step 4: Mount partition command:

mkdir /data

mount /dev/sdb1/data #Mount sdb as/data

Step 5: Write the information to fstab and let the system turn on automatic mounting.

Command: echo/dev/sdb1/data ext4 defaults 00/etc/fstab
